Qt Property Browser library - notice on edit conclusion

[nroberts]

Decided to go ahead and paste directions for a fix here too:

So, here's the half-ass fix I came up with:

I added a "commitItem(QModelIndex)" function to the private thing in the TreePropertyBrowser. Then I call that from the delegate when the setModelData() function is called.

This then finds the property, calls a new function I added to the AbstractBrowser to fetch the factory for a property and then tells the factory to "commitProperty(QtProperty*)".

This function is an empty virtual at the base and in the LineEditFactory I override it to apply the property change, which generates the valueChanged() signal.

With these changes in place the user is able to back out of the edit by hitting the ESC key and I get notified iff they commit the property change by hitting RETURN, focus changing, etc...

Only works for the tree version at the moment. Probably won't bother trying to make the rest work. In fact I'm probably going to throw this library away and just use the QTreeView myself. IT behaves the way I want, this thing had to be uber-hacked to get the behavior BACK.

Oh, and the LineEditor's createEditor function has to be edited to remove the connection to textChanged(). To get the correct behavior the property has to remain unchanged until the commitProprty() request is made.
